01Capacity Planning
Capacity Planning in LPIC-2 201-450 tests whether you can measure CPU, memory, disk and network consumption, establish a baseline, and use trends to predict exhaustion. The exam favors interpreting tool output over memorizing product names.
324 words, about 2 min02Linux Kernel
Linux Kernel questions in LPIC-2 201-450 cover building and installing a kernel, generating initramfs, and controlling loadable modules and parameters at boot and runtime. Source is commonly under /usr/src/linux-<version ; .config holds choices made with make menuconfig or make xconfig .
271 words, about 1 min03System Startup
System Startup covers the path from firmware through the boot loader and kernel to PID 1, plus the targets and recovery modes an administrator uses when normal boot fails. Firmware loads the boot loader, which loads kernel and initramfs; the kernel then starts init or systemd.
254 words, about 1 min04Filesystem and Devices
Filesystem and Devices tests creating, mounting, checking, growing and limiting filesystems, plus the device interfaces that expose kernel state. mkfs.ext4 and mkfs.xfs create filesystems; e2fsck checks ext4 and xfs repair checks XFS.
268 words, about 1 min05Advanced Storage Device Administration
Advanced Storage Device Administration covers software RAID with mdadm, LVM's physical-volume/volume-group/logical-volume model, and the device-mapper layer beneath both. mdadm --create /dev/md0 --level=5 --raid-devices=3 /dev/sdb1 /dev/sdc1 /dev/sdd1 builds a redundant array.
273 words, about 1 min06Networking Configuration
Networking Configuration tests interface addressing, routing, name resolution and troubleshooting with modern Linux tools, including how to make runtime changes persistent. ip link shows interfaces; ip addr add 192.0.2.10/24 dev eth0 adds an address; ip route add default via 192.0.2.1 sets a gateway.
278 words, about 1 min07System Maintenance
